I've got the K240 MkII's and really like them but I'm not exactly trusting myself enough (after one mix with some rather negative reviews) to vouch for them, wholeheartedly.

Haha

Well I've still got the 271's but they're closed backs and I don't really like mixing on them too much.

From what I can tell, the K240 Studio and K240 Mk2's are virtually identical apart from a few peripherals and some gold stickers. So the question really is what's the difference between the K240s and the K141's

I think I may just 'fcuk it' and go for the K702's instead.

Or maybe the Sennheiser HD650s

Not gonna get a chance to listen before I buy though.

im in the market for a pair to mix on myself, the internet is mixed with a cluster fuck of threads on which cans to choose for the job, specially when it comes on judjing the low end, id take a chance with the akg 701's (cryo said they were good) or those sens..

There doesn't seem to be any relevant reviews on the HD650 or K702, just those pointless headfi ones where they just ramble on about listening to jazz on them.

I suspect either will perform the task well.

The HD600 are meant to have a more neutral sound than the HD650, from what I read on some headphone forums.

Lot of people say the 702 sound is almost to sharp and clean leaving the low end sounding kind of thin, it might better for jazz and orchestra, but I don't know I'm just basing this off what people have said on forums.
